TL;DR: In this article, the authors presented the discovery and characterization of two ultra-short microlensing events identified in data from the Optical Gravitational Lensing Experiment (OGLE) survey, which may have been caused by free-floating or wide-orbit planets.

TL;DR: In this article, the authors reported the discovery of a sub-Jupiter mass planet orbiting beyond the snow line of an M-dwarf most likely in the Galactic disk as part of the joint Spitzer and ground-based monitoring of microlensing planetary anomalies toward the Galactic bulge.

TL;DR: In this paper, the authors reported the discovery of a Spitzer microlensing planet OGLE-2018-BLG-0596Lb, with preferred planet-host mass ratio q ~ 2 × 10^(−4).

TL;DR: In this article, the 2L1S/1L2S degeneracy problem was shown to exist over a much wider range of conditions than those considered by the theoretical study of Gaudi (1998).
